•A zinc(II) porphyrin dyad bearing a bipyridine moiety was synthesized.•ET from the excited state of the porphyrin to a bpy moiety occurs in the presence of Cu2+.•A photoinduced ET mechanism is proposed based on the transient absorption data.
A zinc(II) porphyrin complex bearing a bipyridine moiety at the periphery was synthesized. The singlet excited state of the complex was found to be quenched by Cu2 + in methanol, and the photoinduced electron transfer from the excited state of the porphyrin to the bipyridine moiety in the presence of excess Cu2 + ion was observed using a transient absorption technique. The relatively long lifetime of the charge-separated state was ascribed to the slow electron exchange reaction of Cu(II)/Cu(I) couple bound to the bipyridine unit.
